Their effects have been transformative to the lives of many of those living with CF. As the reach of CFTR modulators expands, new questions arise about their role beyond approved clinical indications for people with CF. One such area of growing interest is the use of CFTR modulator therapy during pregnancy to treat suspected meconium ileus, a particularly severe fetal and immediate postnatal manifestation of CF. In this review, we summarize the current data about use of CFTR modulator therapy during pregnancy, including reported effects in pregnant persons and their offspring. We describe the potential of this in utero therapy to prevent meconium ileus and to maintain exocrine pancreatic function in infants with CF. However, these potential benefits must be weighed carefully with the known and potential risks of CFTR modulator therapy. We address ethical implications and important knowledge gaps related to prenatal CFTR modulator use during pregnancy. Further evidence is needed to determine best practices for CFTR modulator use during pregnancy.</p>","PeriodicalId":19465,"journal":{"name":"NeoReviews","volume":"27 3","pages":"e157-e169"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147322051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condition often presents during childhood or adolescence but can be identified in neonates, particularly when there is a positive family history. Early recognition is critical, as timely intervention with beta-blockers and avoidance of QT-prolonging medications can prevent life-threatening events. We report the case of a full-term neonate born via cesarean section to a mother with congenital long QT syndrome (LQT2) and a strong family history of arrhythmic events. On day 1 of life, screening electrocardiogram (ECG) revealed a markedly prolonged corrected QT (QTc) prompting neonatal intensive care unit admission for further monitoring and evaluation. Propranolol was initiated, resulting in gradual QTc improvement over the first week of life. Genetic testing confirmed LQT2, with a pathogenic KCNH2 variant identified. The infant remained clinically stable and asymptomatic throughout hospitalization. The diagnosis of LQTS relies on a combination of ECG findings, clinical history, and genetic testing. Beta-blockers are the first-line therapy, and avoiding QT-prolonging medications is critical. In neonates, early recognition and treatment are vital to prevent arrhythmias. This case highlights the importance of early neonatal ECG screening in the setting of a family history of LQTS and emphasizes the need for multidisciplinary approach to optimize diagnosis, treatment, and counseling.</p>","PeriodicalId":19465,"journal":{"name":"NeoReviews","volume":"27 3","pages":"e184-e187"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147322049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we explore neonatal growth and nutrition in LMICs and identify key strategies that clinicians can adopt to optimize the use of available enteral and parenteral nutrition resources. We address the following approaches: (1) when and how to use alternative fortifiers if infant formula is cost-prohibitive, (2) strategies to optimize intravenous fluids in the absence of total parenteral nutrition, (3) nonfeeding interventions to optimize growth, and (4) discharge feeding strategies and ongoing growth assessments for extremely low-birth-weight infants.

Each phenotype presents with distinct hemodynamic features and clinical implications. Although pulmonary vasodilators such as inhaled nitric oxide remain a cornerstone of therapy for PH, their efficacy and safety vary significantly depending on the underlying phenotype and etiology.

We present 2 cases of fetal CPAMs with dominant cysts that posed unique challenges during the pregnancy. The first had an early presentation at 13 weeks' gestation, and the second had a rapidly increasing CPAM volume ratio. After careful consideration, both pregnant individuals underwent fetal interventions with placement of thoracoamniotic shunts. The subsequent care during the pregnancies and in the neonatal period was complex and required a multidisciplinary approach to care. These cases highlight the nuances of diagnosing and managing CPAMs in utero and after delivery.
